HP 564 - PRINT QUALITY / POOR PRINTING / FADED TEXT / MISSING COLORS__PRINTHEAD FLUSHING
Regarding your recent inquiry about the HP 564XL cartridge print quality problems (fade - no ink hitting
the paper) with your HP Photosmart 7515 printer, unfortunately unlike most printers found in the
market, this particular HP printer model series allows cartridges to run beyond the cartridge empty state
and subsequently causes a deprime and/or ‘drying out’ of the built-in printhead. Also, infrequent
printing can also lead to PRINTHEAD drying and many of the older printer models have a common
tendency to suffer PRINTHEAD ink clogging, particularly with the black ink.
The good news is that this type of condition is completely recoverable (in most cases) – please perform
the recovery steps outlined below, in order. In most poor print quality cases, Step 1 usually provides a
resolution, however you may need to jump straight to Step 5. (PRINTHEAD FLUSHING, SEE VIDEO HERE -
http://inkjet411.com/?page_id=2412 ).
NOTE: 'LOW INK' or 'EMPTY INK' messages, “Empty” and “Low Ink” alerts are COMPLETELY NORMAL for
all HP 564 (or 564XL) ink cartridges which have been refilled! While at first this may be an unusual
workflow, it does allow print operations to proceed. Only brand new ink cartridges support ink l evel
monitoring. Please watch video at the following link which explains normal operation when using refilled
ink cartridges: http://inkjet411.com/?page_id=2317
1) In most cases, there is likely trapped air and/or numerous air bubbles in the printer ink port(s), so
you should perform a "Clean PrintHead" procedure from your printer control panel 'TOOLS MENU',
1 to 3 times (repeat back-to-back). To avoid wasting too much ink right out the gate, we suggest
you FIRST REVIEW all procedures below, along with the video at the following link, and then
perform the tasks described below to recover the ink system: http://inkjet411.com/?page_id=1983
2) A complete lack of printing is typically not a single cartridge problem, but is either the fluids
interface into the PRINTHEAD* (foam connections are dry), electrical connectivity or an electrical
failure of the PRINTHEAD itself. Please follow the steps at the following link to eliminate all
variables: http://inkjet411.com/?page_id=1451
NOTE 1: If one or more the colors were previously dry fired during printing (i.e. if you continued printing
using only a few colors, then down to one, air may have been accidentally ingested into the ink lines
between the cartridge(s) and PRINTHEAD. To recover from this problem, you may have to run the "Clean
